Hey all,
So I've had this XFX R9380 for a few months and no matter what I mess around with I can't stop these very frequent FPS drops in all games (LoL, CSGO, Rocket League, Overwatch ect.). Always drops down to around 20FPS from 60 in games with a cap or about 250 in stuff like CS. I've been trying to keep an eye on GPU-Z and it seems like the GPU core clock is dropping randomly and the GPU is suddenly spiking to 100% usage. My fan rates never get above 66% but that doesn't seem to be the problem because my temps rarely even reach 70oC. The only wuirk is I think that my bench scores on heaven benchmark look reasonable enough but that's synthetic benches for you.

I'm fairly sure there's nothing wrong with the rest of my system as it ran all of these fine with my previous card (an HD6950) however I'm open to suggestions and will post full specs below.

I've tried upping the power limit in crimson, all the drivers have been scrubbed with DDU and reinstalled multiple times, no luck.

So unless anyone can give me some pointers to something I may have missed I suppose I'll have to RMA it :/

This has been over the course of several software revisions so I'm pretty sure it's not that.
